Strap for Automatic Hi Beat 36000 GMT Special White Gold / Silver / Strap

The lug width of the SBGJ207 is 20mm. This dimension represents the contemporary standard for cases between 38mm and 40mm. To verify compatibility, measure the internal distance between the two upper lugs of the case: the value must be exactly 20mm. A strap with an incorrect lug width will not fit properly and could damage the case lugs.

Alligator leather in black or dark brown represents the formal choice par excellence, as the natural grain texture reflects the minimalist essence of the design. For those preferring a patina that develops over time, vegetable-tanned calf leather offers that chromatic evolution that transforms the strap into a personal signature. Shell cordovan represents a middle ground between formality and longevity. For sporty uses, a cotton NATO strap maintains the instrumental character of the mechanical movement.

Changing the strap requires the use of a spring bar tool or specific instruments to extract the attachments from the case. Gently unscrew the pins that secure the integrated bracelet to the sides of the case. Once the original lugs are removed, insert the pins into the new strap and secure them to the case, ensuring they are perfectly aligned. If you are not experienced, we recommend having the operation performed by a professional watchmaker to avoid damage to the delicate white gold lugs.

Yes, the SBGJ207 is fully compatible with quality aftermarket straps provided they have a 20mm lug width. The contemporary horological community offers a wide selection of artisanal straps in alligator, calf, shell cordovan and synthetic materials that fit perfectly to this model. The lug depth (approximately 3.5mm) is a constructive standard that ensures compatibility with most straps made according to European craftsmanship standards.

The lifespan of a natural leather strap depends on the material and frequency of use. An alligator or shell cordovan, if properly maintained, maintains structural integrity for 5-7 years of daily wear. Vegetable-tanned calf, whilst less resistant, stands out for that fascinating patina that develops over time. A cotton NATO strap can last 2-3 years before needing replacement. The standard warranty provided by professional ateliers covers 18 months of normal use, guaranteeing construction quality and product longevity.
